330W AC Adapter for Razer Blade 18

This 330 watt AC adapter replaces the original charger for Razer Blade 18 2024 laptops. It supports the RZ09-0509 model with the i9-14900HX processor. The unit accepts 110 to 240 volt input for worldwide use. It is a direct replacement for the RC30-0484 power supply.

Output specification determines compatibility

The adapter delivers 19.5 volts at 16.92 amps for a total of 330 watts. This exact voltage and current match is the single specification that decides whether the charger will power the laptop correctly. Using a lower rated supply will cause throttling or failure to charge under load.

Capacity and headroom for high performance models

The 330 watt rating comfortably handles Blade 18 configurations equipped with RTX 4080 or RTX 4090 graphics. It also supports the earlier 2023 Blade 16 and Blade 18 models using the RZ09-0483 and RZ09-0484 series. Buyers needing a charger for lower wattage ultraportables or non Razer laptops should look elsewhere.

Questions about this item

Will the 330 W rating actually power a Blade 18 2024 with an i9-14900HX and RTX 4090 under full load?

Yes, the 330 W output matches the factory specification for the RZ09-0509 model with i9-14900HX and RTX 4080 or 4090 graphics, so it delivers the same headroom as the original supply.

Does the barrel connector follow the Razer RC30-0484 pinout and voltage so it seats securely?

The adapter outputs 19.5 V at 16.92 A through the same RC30-0484 connector used on Blade 16 and 18 models from 2023 and 2024, ensuring a direct fit.

What AC input range does the brick accept for international travel?

The unit accepts 110-240 V input, so it works on mains worldwide without a voltage converter.
